IMPROVEMENT IN OZONE-GENERATORS.

Specification forming part of Letters Patent" NoA 136,512, dated March4, 1873.

To all whom Iit may concern:

Buffa1o,in the county of Erie and State of New v York, have inventedcertain new and useful Improvements inA Ozone- Generators, of which thefollowing is a specification:

This invention relates to devices for generating ozone, and consists inproviding a selfacting machine, whereby the water used for washing isutilized to produce and force in the air necessary to the generation ofthe ozone in the retort. It further consists in the construction of thegenerating-chamber for its better protection; also, in the constructionof the washing and purifying `vessels to more thoroughly accomplish thework. It furthermore consists in a double self-acting pump, whichsupplies both air and water by one operation, as hereinafter described.

In the drawing, Figure l is a sectional elevation of the whole machine.Fig. 2 is afront eleva-tion, part in section. Fig. 3 is a plan, showingthe connection between the retorts, &c.; Figs. 4 and 5, detail views;Fig. 6, a plan of the perforated plate or diaphragm; Fig. 7, an enlargedview of the discharge-pipe.

A is a frame-work, in which is placed the air and water tank orreservoir B.v Secured to the top of this tank is a double-barreled pump,C G', supplied with plungers a a, whose rods b b are connected togetherby means 'of a rope or chain, c, which passes upward over a pulley, d,(see Fig.2,) so that one plunger in going down pulls the other up, andvice versa.. The tops of the pump-barrels are connected together by ashallow dish or cup, e, to prevent overow. Attached.v to thepump-barrels in front and just below the center are two pipes, D D,whichlead downward into the bottom of the tank B, as shown. Just below thesepipes, at the bottom of the pumps, are two smaller pipes, EE, whichralsolead into the bottom of the tank B; their use to be hereinafterexplained. This arrangement is for the purpose of discharging both airand water into the tank, as both are important element-s in makingozone.

The construction and working of the double pump are as follows: Abovethe two pumpbarrels is a discharge-pipe, j, pivoted to a hanger, G, andattached. to the water-supply pipe F, which connects with a hydrant orreservoir. The discharge-pipe f is thus pivoted so that it will vibrateto throw the water into either pump-barrel desired. To accomplish thisit has attached to it a double-forked lever or bar, g, whose endsinclose the piston-rods b b', and by means of lugs or catches h h on therods, serve to throw the pipe f over from one pump to the other, thuschanging the direc tion of the water from one barrclto the other everytime the plungers rise and lower.

The operation is as follows: The water will run into one barrel from thepipe f until it is nearly full, when the weight of the water will causethe plunger to descend, and so draw the other up. When the plunger `hasfallen far enough to pass the opening to the pipe D, or assume theposition shown in Fig. 1, the water will run out into thetauk B. In themeautime the other plunger in rising has drawn the other barrel belowthe plungerfull of air, introduced through the air-valve pipe H, (seeFigs. l and 5,) and when it has reached its highest limit the weight ofwater in the other barrel will reverse the pipe f, and cause the waterto run into the other barrel, which, when it is full, will descend asthe other did, forcing the air in the ybarrel beneath the plungerthrough the pipes into the tank, where the air will of course risethrough the water to the top. When the second plunger rises-it alsodraws in its supply of air, which it also discharges when it descends,and so the action goes on.

The pipes D D and E E carry both air and water, forcing the air downf1rst,and then the water following by its own weight. The lat ter alsocarries oli' any water that might otherwise collect in the bottoms ofthe pumps, which, if allowed to stand or accumulate, would interferewith the workin g of the plungers. These plungers a a are of peculiarconstruction, and consist of a ring,`z`, somewhat smaller than thepump-barrel, and supplied with a series of holes, j j, and surroundedwith a loose leather or rubber packing-piece, la, which is held at thetop by a ring, l, and at the bottom by a disk, m, in which the rod bissecured. The water is allowed to pass through the perforationsj in thering i, and thus expand the leather or rubber packing k, and thus keepit always full of water and packed tight; and the greater the pressure,and, con-,

sequently, the more need-of a secure packing, the tighter itwill hold. His an air-pipe, in the top of which a valve is set, which consistsmerely of a sharp-edged valve-seat, upon which a spring-valve rests, andthus secures a tight joint witha very small amount of fric# tion. Thissupplies air to the pump-barrels. The area of the feed-pipe fis muchsmaller than pipe D, so that the latter will discharge much sooner, andthus prevent the possibility of one plunger descending before the otherhas discharged. The tank B is supplied with a siphon, I, which keeps thewater in the tank always at the same level, as indicated by dotted linesa in Fig. 1, and so always leaves a space at the top for air, while atthe same time no air can escape. Beneath the tank B is a division-plate,J, which forms the bottom of a glass retort or generating-chamber, whichsets upon a rubber packing-ring, p, between two annular rings q q', (seeFigs.1 and 3.) This retortis formed with an inner chamber of glass, o',having an outside metal wall or case, K, with a space, s, between it andthe glass retort i', top and sides as well, which is n'lled inwithplaster of Paris, or its equivalent, to strengthen and protect the glassfrom accidents, Ste. In opposite sides of the case K are two openings,t, having sliding doors or covers to enable the operator to see thephosphorous sticks L (see Fig. 1) and ascertain whether the generationis progressing. The case or metal wall and filling are importantfeatures of my invention, as without them the glass retort is almostcertain to break, and Vthus leave the phosphorus exposed, when it wouldimmediately ignite. u u are two small pipes which enter thegenerating-chamber r through the bottom of the plate J, and which areconnected to two other pipes, one of which, M, is connected to thebottom of the tank B for supplying water to the generating-chamber,while the other, N, connects with the top of the tank, and. thussupplies air to the retort. P1P2 P3 P4 are the four glass vessels orwashing-chambers cemented between annular rings to the division-plate J,with a hole, v, leading into each vessel. Beneath each of these chambersis a metal cistern or vessel, w, in the center of which is a perforatedplate or diaphragm R, having a portion of its center withoutperforations, as shown in Fig. 6.

1 2 3 4 5 are short tubes or pipes which connect the vessels P to withthe generating-chamber. The iirst pipe, 1, passes from the retort rdownward and upward into the center of the iirst cistern w and endsbeneath the center or solid part of the perforated plate B.. The nextpipe, 2, passes from the first chamber P1 downward through the cisternw1 and upward through the bottom of the cistern wz, 4and ends beneathits plate R precisely like pipe 1 in cistern w1. The other pipes, 3 and4, are connected to the other chambers P3 P4 in a similar manner, asshown. The last or exit pipe 5 passes from the chamber P* downward andupward, and ends in the bottom of a smaller metal dischargechamber, S,into which a smaller pipe; w, sets, having its bottom made ilaring andperforated, as shown in Fig. 7 which sits over the end of the pipe 5,the object to be presently explained.

The operation of the entire machine is as follows: The water flowsthrough the pipe F, and its power or weight is used bythe pumps C C toforce air into the reservoir B. By this simple means a pressure of airis always had in-the top of the tank B, as hereinbefore described. Thewater and. air then pass, by means of the pipes M N, into the bottom ofthe retort or generating chamber r, where the air will always, ofcourse, rise to the top, while the water remains at the bottom 5 and thequantity will be so regulated by stopcocks, &c., that it will never riseabove a certain limit, as indicated by the dotted lines in the chambers.The water and air then acting on the phosphorus L generatesphosphoric-acid gas,77 which contains a very large percentage ot' ozonein an impure state. To separate and purify it, it is then conducted, bythe pipe l, downward through the water and upward into the first cisternwl, where it is thrown forcibly in globules against the plate It, andstriking the solid portion in the center distributes itself and isthrown up through the perforations, and is carried in smaller globulesinto the glass-chamber P1, where it rises as a gas to the top above thewater. This action serves to partially purify it; but to make itthoroughly pure it is passed, in a similar manner, through the remainingthree chambers, and finally emerges into the discharge-chamber S, butstill mixed with the water, into the flaring end of the pipe fr. Theozone then rises upward and passes out of this pipe, while the water andphosphoric acid are carried off through the perforations in the pipe x,and, rising to the top of the divisionplate J, are carried oft' by awaste-pipe or other device.

I do not claim the manner of generating ozone, but only my importantimprovements to supply the necessary amount of air and water to thegenerating-chamber, and the means whereby' the ozoneis thoroughly washedand puriied, more particularly using the water to produce the necessaryair and making a self-acting machine. I do not claim producing ozonefrom phosphorus under pressure of water and air, as such is shown anddescribed in the Letters Patent of P. A. Royce, dated September 12,1871, No. 118,976.
